IMPROVEMENT IN CURTAIN-CORD REVTAINERS.

Specication forming part of Letters Patent No. 149,861, dated April 21,1874; application led January 13, 1874.

To all ohom it may concern:

Be it known that I, HENRY HoLoRoET, of Media, in the county of Delawareand State of Pennsylvania, have invented certain Improvements inCurtain-Gord Retainers, of which the following is a speciication:

My invention consists of a coiled spring with two curved projectingarms, the coil being at the intersection of the arms. The arms areconnected by a sliding cross-bar, in which is formed an eye for thecord.

Figure l is an elevation, showing the ordinary flxtures for a curtain,with my improved cord-retainer. Fig. 2 is an end view of the same.

Similar letters in the drawings refer to like parts.

B is the roller, on which the shade or curtain is wound. On the right-isa grooved pulley. Each. end of the roller is supported by brackets b b.D is the cord. Fis the cordretainer, and is constructed of spring-wirein the following manner: An eye is formed of two ormore coils, and theends c a are curved up in the form'of the letter V with the tops turnedover, as shown in the drawing. his

the cross-piece, which is also made of Wire, and is formed with an eyein the center, anda small one at each end, through which passes the endsa a.

My improvement is applied in the following manner: The cord D is passedover the pulley 'on the roller, and then through the eye in thecross-piece h. It is then drawn tight till the cross-piece h is abouttwo-thirds up the arms a. a, when an oval-head wood-screw is put throughthe eye formed by the coils and screwed into the window-casing E. Thecoiled spring and curves in the arms a. a will draw down the cross-pieceh and keep the cord tight through all changes of temperature andatmosphere, and will retain the curtain in any position it may beplaced.

In a curtain-cord retainer, as described, the combination, with` acoiled spring provided with curved arms a c,of the sliding cross-pieceh, as and for the purpose specified.
